Módulo de relé para calha DIN Shelly 4 canais Pro 4PM Wi‑Fi, 4 canais, AC 110–240 V, medição de potência e energia, montagem em calha DIN

The Shelly 4Pro PM is a DIN-rail mountable 4-channel relay with Wi-Fi, Bluetooth and LAN connectivity. It provides independent switching of four circuits and integrates precise power meters for separate consumption measurement per channel. The device includes a 1.8" color display with navigation keys, supports operation via the Shelly Cloud smartphone app (Android, iOS) without an external hub, and is compatible with common automation platforms. Designed for indoor installation, it offers protective functions such as over-power and over-voltage protection and supports loads up to 16 A per channel (maximum total 40 A).

Advantages

The Shelly 4Pro PM combines four relays and four dedicated power meters in a single DIN-rail module, enabling accurate monitoring and control of multiple circuits from a single device. Multiple connectivity options (Wi‑Fi, Bluetooth and LAN) allow flexible integration into home and commercial automation systems. The built-in 1.8" color display with navigation keys simplifies local setup and status checks, while app control via Shelly Cloud enables remote switching and real-time energy monitoring. Protective features and support for automation platforms increase safety and interoperability.

How to use

Install the Shelly 4Pro PM on a standard DIN rail inside a distribution board following local electrical regulations and safety practices. Connect supply voltage (110–240 V AC) and wiring for each load to the corresponding relay outputs. Power on the device and use the on-board display or the Shelly Cloud app on a smartphone (Android or iOS) to complete initial setup and network configuration. After setup, control each channel remotely via the app or integrate the module into supported automation platforms for scheduling and rule-based automation. Monitor per-channel consumption through the app or local display.

Recommendations

For reliable operation, ensure wiring and installation are performed by a qualified electrician and avoid loading any single channel above 16 A. Place the device inside an appropriate enclosure for indoor use and maintain ambient temperature within the 0–40 °C operating range. Use the LAN or Wi‑Fi connection for stable remote control and regularly update device firmware via the Shelly Cloud app.
